The increase of air humidity would increase the soil water and decrease the soil
temperature. Monteith et al.

stated that the shading increases the efficiency of water used
by the plants below, by decreasing the evapo- transpiration of the plants below.
The soil chemical character of those three research location were not so much different
and it could be categorized into less fertile soil Table 4. Soil in Tekil, Sawangan and Saradan
were latosol. NPK content and organic substances in those three research field
showed the low availability of the elements. However, KTK in Saradan was higher than that
of in Tekil and Sawangan.

Generally, the dose of the organic fertilizer had an effect on the entire growth
and yield parameter in Sawangan and Saradan but of the plant height, root length and
reserpina in Sawangan Table 5.The increase of the root result was not always enclosed by
the increase
of secondary
metabolite reserpine Figure 1.

stated that there is a dilemma for the plant growth and the
alkaloid forming. To stimulate the forming of defense function like the secondary metabolite
it would needs an environment pressure condition. However, enough fertilization and
soil water is able to increase the alkaloid production

, therefore the fertilization could affects the reserpine amount as proved by the
present data. We found a direct relationship between the leaf number and the root dry
weight r = 0.49. The increase of the leaf number was followed by the increase of the
root dry weight Table 6.
